BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-train passenger calling for automatically and promptly and reliably calling an in-train passenger from a ground-based general subscriber without requiring a train stand operator or a train operator. The present invention also relates to an in-train passenger call communication method for automatically and promptly and reliably calling an in-train passenger from a ground-based general subscriber and for making a call with the passenger.

[0002]

2. Description of the Related Art Up to now, "Train Radio" (Japan Railway Technical Association, published May 10, 1994, p. 72)
As can be seen from the Shinkansen train radio system described in (1) to (75), it is possible for passengers in the train to call general subscribers on the ground by dialing operations that are performed by ordinary telephones. On the contrary, in order to call passengers in the train from general subscribers on the ground, a train stand operator and a train operator are intervening. This is because passengers on the train cannot be called directly from the ground subscribers.

Here, the connection sequence (operating by the actual Shinkansen) according to the prior art from calling the passenger in the train from the general subscriber on the ground to making a call with the passenger is as follows. That is, the ground station configuration is shown in FIG.
The mobile station configuration is shown in FIG. 8. The connection sequence will be described with reference to FIGS. 7 and 8 while referring to FIG. 7 and FIG. 8. General subscribers on the ground can communicate with passengers in a train via the public network. At the time of execution, first, a general subscriber dials a telephone number corresponding to the train stand 3 from the telephone 1 to call the operator of the train stand 3 via the general subscriber exchange 2 (call origination 1). Self-identification information (telephone number, name, etc.), called train number, called passenger information (name, address, etc.) are declared to the operator as an in-train passenger calling application request (information transmission 1). ). afterwards,
The call from the general subscriber is temporarily disconnected (disconnection 1), and the train operator is called by the operator of the train stand 3 based on the called train number (call origination 2). The call is general subscriber exchange 2, train radio voice device 4, LCX device 5, LCX (Leaky Coaxial Cabl).
e: a leaky coaxial cable laid along the railroad track), the antenna 6, the wireless device 7, the in-train exchange 8, and the in-train operator terminal 9 route. By the way, after the train passenger who has called up the train passenger, the operator of the train stand 3 conveys the in-train passenger calling application request content from the general subscriber as it is, and after the passenger calling request is made (information Transmission 2), the call is once disconnected by the operator of the train stand 3 (disconnection 2). After that, the train operator calls the called passenger by in-car broadcasting (including name and address) (in-car broadcasting), but the in-car broadcasting prompts the called passenger to train from the nearest public telephone 10 in the train. The insider is called (response 1) and is declared to be the person called by in-vehicle broadcasting. Based on this declaration, after the passenger in the train confirms that the passenger is the person who was applied by the ground general subscriber, the call with the passenger is temporarily disconnected (disconnection 3). . The passenger who is called until the call from the train operator is made by the public telephone 10 again,
It is in a standby state on the spot.

In the subsequent operation, the train operator takes a route opposite to the above, calls the operator of the train stand 3 (calling 3), and then the passenger. After the name and address of the passenger and the telephone number and name of the general land subscriber have been transmitted (information transmission 3), the public telephone 10 waiting for the passenger who is called in advance is called (call 1). When the passenger responds to the call from the public telephone 10 (response 2) and the train operator is informed that he / she is the called person, the train operator is already connected by calling 3 and is in the hold state as it is. The call to the call placed on hold (reserve 1) is performed (relay 1), and during that time, the operator of the train passenger 3 requests the general subscriber from the train subscriber 3 through the general subscriber exchange 2. Although the call is made (call origination 4), it remains in the hold state until the relay 1 is completed after the call response from the general subscriber (holding 2). Eventually, after the relay 1 of the train stand 3 confirms that the relay 1 has been completed, and the relay of the general subscriber telephone 1 and the public telephone 10 in the train is performed (relay 2), at this point, it is the first time on the ground. Calls can be made between subscribers and passengers on the train. After that, when the call ends, the operator of the train stand 3 confirms the end of the call (disconnection 4), and the line is restored (disconnection 5). In addition to the above, for example, "Public public exchange for Tokaido / Sanyo Shinkansen train radio" (Hitachi Review 1990.9, Imai, Yubara, etc.)
Is mentioned.

[0005]

However, in the case of the above-mentioned prior art, when a passenger on a train is called from a general subscriber on the ground via a public network, a train stand operator and a train operator are involved. In addition, it is necessary for the train switch operator to verbally convey the request request for passengers to call in the train to the train operator, which may cause an error in the transmitted contents, and the passengers in the train call It takes a lot of time to be done. Such a problem is also seen in the subsequent general subscribers and the relay connection between passengers in the train.

[0006] A first basic object of the present invention is to provide an in-train passenger calling method capable of calling passengers in a train automatically, promptly and reliably from general subscribers on the ground. A second basic object of the present invention is to provide an in-train passenger call communication method capable of calling passengers in a train automatically and promptly and surely from a general subscriber on the ground and making a call with passengers in a train. To serve.

[0007]

SUMMARY OF THE INVENTION The first object is basically to provide a telephone number which is sent as data from a general subscriber in a reception device called by the general subscriber via a general subscriber exchange. After the identification information of the general subscriber including, the train number of the called party and the identification information of the called passenger are automatically accepted as an in-train passenger calling application request, the line with the general subscriber is disconnected, The in-train passenger call application request is simultaneously transmitted to each train as a radio frequency signal on the LCX via the train radio data device and the LCX device, while the radio frequency signal received via the LCX antenna is transmitted to each train by radio. After being demodulated in the data signal band by the machine, it is transferred to the in-train data device, and the called train number included in the in-train passenger calling application request is the in-train data. On condition that matches the train number 置内 the preconfigured, said column-vehicle passenger call application request is achieved by being displayed as a visible / voice call message information in the train.

[0008] The second object is also basically that, in a reception device called from a general subscriber via a general subscriber exchange, the general information including a telephone number transmitted as data from the general subscriber.

A function of automatically calling a general subscriber through a general subscriber exchange is mentioned.

The present invention will be described in detail with reference to FIG.
FIG. 3 shows a ground station configuration according to the present invention, and FIG. 3 shows a mobile station configuration according to the present invention. As shown in FIG. 2, the structure of the ground station is such that the general subscriber side has its telephone terminal 1 as its terminal.
And a personal computer 11 for inputting a message, and these telephone 1 and personal computer 1
One of each of them is selectively accommodated in the general subscriber exchange 2 via the switch 13, while the personal computer 11 is provided with a digital / analog data modulation function and an analog / digital data demodulation function. It is accommodated in the general subscriber exchange 2 via the modulator / demodulator 12. The general subscriber exchange 2 also has
In addition to accommodating the reception device 14, the in-train passenger calling application request from the personal computer 11 is automatically received. The in-train passenger call application request from the reception device 14 is also transmitted to the train radio data device 1.
In addition to being subjected to the identification processing in 5, the LCX device 5 transmits them to each train simultaneously via the LCX. On the other hand, L
The connection request accompanied by the general subscriber telephone number transmitted from the called train via the CX / LCX device 5 is transferred to the reception device 14 via the train radio voice device 4, and then accepted based on the general subscriber telephone number. From the device 14, the telephone 1 is called through the general subscriber exchange 2, and then the telephone 1 and the train-side dedicated terminal are connected after waiting for a calling response from the telephone 1.

On the other hand, as shown in FIG. 3, the mobile station configuration is such that an in-train passenger calling application request from the LCX is an LCX.
The train number which is received in the antenna 6 for use, transferred to the in-train data device 16 via the wireless device 7, and the called train number included in the in-train passenger call application request is the preset train number. The passenger in-train call application request is displayed in the train, for example, on the in-train display panel 17 as visible call message information on the condition that it matches with. Further, in a state where the calling message information is displayed, when the display is prompted, the nearest dedicated terminal 18 is off-hook by the passenger in the train who has been called, the off-hook is a connection request and the in-train switch 8 is connected. , The radio 7 and the LCX antenna 6 are transmitted to the train radio voice device 4 already described. Following the connection request, the train passenger voice voice device from the dedicated terminal 18 is called by the passenger in the train called. In FIG. 4, the general subscriber telephone number is transmitted via the same route.

The ground station configuration and the mobile station configuration have been described above. Incidentally, detailed configurations of the reception device 14, the train radio data device 15, and the train radio voice device 4 are shown in FIGS. 4, 5, and 6, respectively.
The configuration and internal operation of each of 5 and 4 will be described with reference to FIG. 1, which shows a connection sequence according to the present invention until a passenger on the train is called from a ground subscriber and the call with the passenger is terminated. At this time, it will be described below together. That is, explaining the connection sequence, if the general subscriber accommodated in the general public network wants to talk with passengers who are on a specific train, after recognizing the train number in advance, The telephone number corresponding to the reception device 14 is dialed from the telephone 1. This allows general subscriber exchanges (hereinafter simply referred to as exchanges)
The reception device 14 is called from 2 (call origination).
When the calling signal from the exchange 2 arrives at the incoming call trunk 141 in the receiving device 14, the incoming call trunk 141
From this, the CPU 1411 is notified that the call signal has been detected. Based on this, the CPU 1411 activates the incoming call trunk 141, so that the exchange 2 is connected between the general subscriber and the incoming call trunk 141. The established communication path is set. At the same time,
The CPU 1411 connects the voice output unit 147 and the incoming call dedicated trunk 141 via the communication path switch 148, and the data output voice guidance is transmitted from the voice output unit 147. The voice output unit 147 pre-stores prescribed voice data (for example, a series of voice guidance data for prompting data transmission from the personal computer 11 etc. such as "This is the customer call center in the train." However, this allows a general subscriber to hear the voice guidance (response voice). In the CPU 1411, after transmitting the data transmission voice guidance from the voice output unit 147, a series of data transmitted from the general subscriber, that is, identification information of the general subscriber including a telephone number, a called train number and a called passenger. In order for the identification information of the incoming call to receive the passenger in-train calling application request,
48, which is connected to the third communication control unit 146 via the modulation / demodulation device 145, and thereafter, the in-train passenger call application request sent from the general subscriber is subjected to reception identification processing (message reception). The general subscriber side is prompted by the data transmission voice guidance, and, for example, in the state where the telephone line is switched from the telephone 1 side to the personal computer 11 side, the personal computer 11 transmits an in-train passenger calling application request to the reception device 14. That is why. After that, in the reception device 14, after the reception and identification processing of the passenger call request request in the train is completed, the incoming trunk 141
The line will be temporarily disconnected by the release of (reception end, disconnection). At that time, in the received in-train passenger calling application request, the telephone number as general subscriber identification information is temporarily stored in the CPU 1411. This is generally sent from the called in-train passenger. It is necessary to confirm that the subscriber's telephone number is the same as the passenger's in-train calling application requesting general subscriber's telephone number. Because it is needed when calling. Incidentally, the in-train passenger call application request may be sent from the push button type telephone by combining push buttons.

As described above, the reception device 14 receives the in-train passenger calling application request from the general subscriber, and the received in-train passenger calling application request is thereafter activated by the CPU 1411. The first being
The data is transmitted from the communication control unit 149 to the train radio data device 15 via a data line (data transmission). In the train radio data device 15, the in-train passenger call application request is received by the reception device communication control unit 151, notified to the CPU 154, and then sent to the mobile station communication control unit 152. The mobile station communication control unit 152 is provided to transmit data to the in-train data device 16 mounted on each train. In the mobile station communication control unit 152, data is transmitted to each of the in-train data devices 16 in a predetermined telegram format. At that time, the call included in the in-train passenger call application request is made. The destination train number is used to identify the train on which the called passenger is boarding. The train number is a number assigned in advance as a unique number for each traveling train, and if this is used as train identification information, only the in-train data device 16 installed in the train on which the called passenger is aboard is An in-train passenger calling application request may be selectively transmitted. As described above, C
The in-train passenger call application request sent from the PU 154 to the mobile station communication control unit 152 is then converted to a radio frequency signal from the radio 153, and the LCX device 5
Is transmitted over the LCX via the (data transmission 2). As described above, since the LCX is laid along the railroad track, the radio frequency signal of each traveling train is received by the LCX antenna 6 and then demodulated by the radio 7 into the data signal band. In addition, in-train data device 16
However, in each in-train data device 16,
The in-train passenger call application request is temporarily stored, provided that the called train number included in the in-train passenger call application request matches the train number preset in the in-train data device 16. In addition, the information is displayed as visible call message information on the train display panel 17 (message display). However, it is possible to display the in-train passenger call application request as voice call message information.

As a result of the above, the in-train passenger calling application request is displayed on the in-train display panel 17 as the telephone number and name of the requesting general subscriber and the name and address of the called passenger. From the display, it is known that the calling passenger is a calling addressed to himself. Therefore, it is necessary and sufficient for the in-train passenger calling method according to the present invention to display the calling. This is because, when a public telephone is installed in the train, the passengers in the train can call the general subscribers on the ground by the dial operation performed by a normal telephone. However, in the in-train passenger call calling method according to the present invention, the dedicated passenger terminal (calling dedicated telephone terminal) 18 nearest to the train passenger is simply off-hooked by the in-train passenger, and the in-train passenger calling request source general subscriber telephone number is By dialing, the in-train passenger calling application requesting general subscriber is called. The calling sequence will be described below.

That is, the dedicated terminal 18 installed in the train is off-hook by a passenger (calling passenger) in the train, and when the off-hook is detected by the in-train exchange 8, the radio 7 is activated and the train radio voice is activated. A connection request signal to the device 4 is transmitted from the wireless device 7 (calling 1). The connection request is transmitted from the radio 7 to the radio frequency signal from the radio 7 to the LCX, and then received by the radio 46 in the train radio voice apparatus 4 via the LCX device 5. In addition, it is sent to the trunk 42 in a state of being demodulated in the voice signal band. The CPU 4 indicates that the connection request signal is received from the trunk 42.
7, the CPU 47 activates the trunk 42 based on this notification to form a communication path with the in-train exchange 8 via the wireless device 7 or the LCX ( Response 1). At the same time, the trunk 42 and PBR (multi-frequency receiver) 4 via the communication path switch 44.
In the state where 3 is connected, the in-train passenger calling application requesting general subscriber telephone number from the dedicated terminal 18 is received. The telephone number received by PBR43 is CP
The data is transferred to the U47, and the CPU 47 receives the telephone number and simultaneously receives the train radio voice device 4 and the reception device 1.
In order to connect the four via voice lines, the communication control unit 45 is activated, the bidirectional trunk connection request is transferred to the reception device 14 (call origination 2), and the trunk 42 and the bidirectional trunk are connected via the call path switch 44. The bidirectional trunk 41 is connected to the reception device 14 by switching and connecting 41. As a result, the communication path is extended to the reception device 14 via the train radio voice device 4. On the other hand, in the reception device 14, the two-way trunk connection request signal from the communication control unit 45 in the train radio sound device 4 and the subsequent in-train passenger call application requesting general subscriber telephone number are the second communication control unit 1410. The CPU 1411 is notified of that fact, and the CPU 1411 activates the bidirectional trunk 143 based on this notification, so that the train wireless audio device 4
And a call-only trunk 142 and a PBOSC (multi-frequency oscillator) 144 are connected via a speech path switch 148. CPU
The general-purpose public line is captured by activating the transmission-only trunk 142 by 1411, and then the PBOSC 144
In addition, the multi-frequency signal corresponding to the in-train passenger calling application requesting general subscriber telephone number is sent from the PBOSC 144 to the exchange 2 from the transmission-only trunk 142 (call 3). Prior to the transmission, the in-train passenger calling request source general subscriber telephone number is compared and collated with the telephone number temporarily stored in the CPU 1411. The requesting general subscriber telephone number is sent as a multi-frequency signal (number confirmation).
This is because if the wrong telephone number is sent from the dedicated terminal 18 as it is, the wrong general subscriber may be called. However, if the general subscriber telephone number of the application request source is automatically generated from the dedicated terminal 18 or the like when the dedicated terminal 18 is off-hook, such a problem can be avoided.

Now, when the transmission of the telephone number from the PBOSC 144 is completed, the CPU 141 in the receiving device 14 is completed.
1 connects the call-outgoing trunk 142 and the bidirectional trunk 143 through the call path switch 128,
On the basis of the reception of the multi-frequency signal from the accepting device 14, the exchange 2 sends a ringing signal to the corresponding subscriber line to ring the bell of the telephone 1. In order to respond to this, when the general subscriber goes off-hook of the telephone set 1, this off-hook is transmitted to the transmission-only trunk 142 in the reception device 14 via the exchange 2, and the CP is also sent.
The U1411 is notified (response 3), and the CPU 1411 activates the call-out trunk 142 based on this notification to form a call path with the exchange 2 (call). At this point, for the first time, the general subscriber who requested the in-train passenger calling application can make a call with the in-train passenger. Eventually, if on-hook is performed on either side with the end of the call, all the call paths are released (disconnected) triggered by this.
